Department of The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date 7 ABSTRACT Previous studies of the properties of electroslag weld metal have been done using electroslag remelted ingots made under welding conditions. This procedure assumes the electrical and thermal regimes of these pro• cesses to be equivalent. To test this assumption an experimental program was devised in which the remelted metal of an ingot and weld made with each of three slag systems was analysed and the mechanical properties examined. The results show that each process imparted different properties to the remelted metal by alloy and inclusion modification. Consequently the above assumption was proved invalid. Special consideration was given to the effect of inclusion composition and overall distribution toward mechanical properties.

This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces. Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, under water and in outer space. Regardless of location, welding remains dangerous, and precautions are taken to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light.

  • Applications and Trends of Electroslag Technology in Japan
    Welding Research Abroad, 32(2):27-34, 1986 APPLICATIONS AND TRENDS OF ELECTROSLAG TECHNOLOGY IN JAPAN Thomas W. Eagar INTRODUCTION Electrosiag welding and casting processes have been used in Japan for approximately two decades, with enerally good success. This report describes the amount of electrostag welding pzrformed In 3apan in 1981 along with typical product applications. It also describes briefly an electroslag casting and an electroslag overlay process, as well as recent trends in the usage of ektroslag technology. A brief discussion of the reasons fw the trends is also included. ELECTROSLAG WELDING Professor Isao Masumoto of Nagoya University reviewed the application of electroslag welding in Japan in 1981 [Masumoto et aZ. (1981 )]. His survey, which does not claim to be comprehensive, but appears to include most of the larger users of electroslag welding, indicates that more than 250 tons of electroslag weld metal was deposited in 1981. This was estimated to be 0.064% of the total volume of weld metal used in Japan; hence, in Japan, electroslag is a specialized process which is used for a limited number of applications. Nonetheless, Japanese industry has a wide range of experience with the process. Welds of 0.3 m to 9 m length have been made in section thicknesses ranging from 16 mm to 2.1 m. Welding currents range from 280 A to 8000 A with joint gaps from 18 mm to 50 mm. Materials welded include mtid steel, high strength steel, stainless steel, and Cr-Mo steels. As can be seen from Figure I, three-quarters of the weld metal is produced by the nonconsumable electrode guide process and most of this is used by the industrial machinery and pressure vessel industries.

  • Recommended Practices for Electrogas Welding AWS C5.7:2000 (R2006) an American National Standard
    AWS C5.7:2000 (R2006) An American National Standard Recommended Practices for Electrogas Welding AWS C5.7:2000 (R2006) An American National Standard Approved by the American National Standards Institute May 5, 2000 Recommended Practices for Electrogas Welding Supersedes ANSI/AWS C5.7-89 Prepared by the American Welding Society (AWS) C5 Committee on Arc Welding and Cutting Under the Direction of the AWS Technical Activities Committee Approved by the AWS Board of Directors Abstract Electrogas Welding (EGW) is a specialized welding process having similarities to the gas metal arc welding (GMAW) or the flux cored arc welding (FCAW) processes for vertical position welding. The electrode deposits filler metal in the cavity formed by backing plates or shoes that bridge the groove between the plates being welded. The elec- trode may be solid, metal cored, or flux cored, and additional shielding may or may not be obtained from an externally supplied gas or gas mixture. The weld is usually completed in a single pass. Fundamentals of the process, including the various methods of welding, are presented. A discussion of equipment, consumables, applications, and metallurgical advantages and limitations is provided. The selection of process variables and operating conditions and typical EGW procedures is then presented. Inspection of welds, and training and qualifica- tion of welding procedures and operators are described. Finally, a troubleshooting guide, safety considerations, and a supplementary reading list are presented. 550 N.W. LeJeune Road,

  • Chapter 13 Processing of Materials
    CHAPTER 13 PROCESSING OF MATERIALS All metal parts and components go through a number of different processes in their manufacture. Most metals, after extraction from their ores, are melted and cast, either as ingots or as castings. Ingots are usually made with a geometric cross section (round, square, rectangular, hexagonal etc. - sometimes with rounded, or mitred comers or with scalloped faces). The actual shape is determined by a combination of metallurgical and econontic factors. They are normally cast into metal moulds to provide rapid cooling and solidification of the metal. An ingot is simply a convenient shape and size for subsequent working of the metal by rolling, forging or extrusion. ---"'- , -- ---- - _.---- Castings are produced by pouring the liquid metal into a specially prepared mould where the metal may solidify and take up the shape of the mould. This shape is made to be as close as possible to the final shape of the part. There are a large number of different casting processes, all of which have in common: • A suitable mould cavity must be prepared. • The size of the cavity must be larger than the fmished size of the part to allow for shrinkage and contraction of the molten mem] as it solidifies and cools. • There must be proviSion for air and gases to escape from the mould as the metal is poured in. • The mould must not unduly restrain the casting as it contracts during cooling. • It must be possible to remove the casting from the mould after solidification, and it must also be possible to remove any residual mould material from the cold casting.
